&MAGNETIC


COMPONENTS

  Sets the x, y and z components of the magnetic field. The default unit
  is the rather unconventional 100 Gauss which does however fits in the
  overall system used by the program. You may also use Gauss or Tesla
  if you prefer.

  If your cell has been entered in polar coordinates, you should ensure
  that both the x and the y components are zero. Only the z component
  may be non-zero.

  Format:

  COMPONENTS  Bx By Bz  [GAUSS|TESLA]

  Examples:

  COMP 0 0 50
  COMP 0 0 5000 G
  COMP 0 0 0.5 T

  (All three are equivalent.)

SUSCEPTIBILITY

  Sets the susceptibility of the gas and the wires. The unit system
  is irrelevant: only the ratio matters. The default settings are 1
  for the wires and 0 for the gas. The magnetic field has clearly
  no effect if the two are equal.
